If u want a real big piece of lead, u can go to a car-wheel rim shop where they have balancing weights for tires. A friend use that on the end of his racket (butt-cap) and it works well. It┤s sticky as hell though!

O! and yea, i ended up uping my racquet about .7 oz heavier. its now 12.3 oz strung, and i made sure balance was kept normal (around 8 points hl). so yea, i put layers at 3 and 9 , 6, and on the handle. works out great! thanks you guys
